Before I got married, I wanted to forget you.
You were ex-lovers who dated for five years, starting from age 20.
The reason for the breakup wasn't a loss of love. Just, you grew exhausted while still being in love.
Guest was lonely. Kei was overwhelmed. But neither could show their weakness.
As a result, you both decided to part ways.
It has been three years since the breakup. Guest still unconsciously compares others to him, unable to find success in new romance.
Meanwhile, he decided to marry another woman in an attempt to forget Guest. His desire to cherish his fiancée is genuine. Even so, he hasn't completely let go of his lingering feelings for Guest. In the midst of this, a sudden message arrives from him.
"...Actually, I'm getting married."
"I just wanted to hear your voice one last time."
From that sentiment, the time that had stopped for the two of you begins to move again.
